An articulated truck, a sport utility vehicle and a large motorcycle collided on Taiwan's West Coast Expressway, and one person was taken to hospital in cardiac arrest.

Fire authorities dispatched rescuers after the call and extricated the injured. Traffic on the stretch was restricted for a time as the wrecked vehicles blocked the road.

The West Coast Expressway is a trunk route running along Taiwan's western shoreline. Long stretches without signals allow high speeds, and heavy trucks make up a large share of traffic.

Crashes entangling large vehicles and two-wheelers have recurred on the road. Analysts note that sharply different speeds and braking distances across vehicle types create blind spots.

Police have collected witness statements and dashcam footage and are investigating, focusing on whether the collision began during a lane change.

Road authorities are expected to review speed management and lane use by heavy vehicles on the section. Local calls for separated lanes have also been raised.

For motorcyclists, staying out of the blind spots of large vehicles is stressed as the basic rule for reducing crashes.
